1. Core Product Advantages: Directly addressing the pain points of high-temperature measurement

✅ Exclusive cooling design, heat-resistant and drift-free

Uses thickened aluminum alloy finned heat sinks / integrated cooling structure to increase heat dissipation area, quickly conducts and dissipates high temperatures from the medium, effectively blocking heat transfer to sensor cores and circuit modules. In high-temperature scenarios that conventional models cannot adapt, this product can operate stably, avoiding large measurement errors, component burnout, and frequent equipment failures caused by excessive temperature, significantly reducing subsequent operation and maintenance costs.

✅ High-precision measurement: Data is accurate and reliable

Built-in imported diffusion silicon pressure core, with measurement accuracy up to ±0.2% FS/±0.5% FS options, high sensitivity and fast response speed, no obvious zero or range drift during long-term operation, ensuring real-time and accurate pressure data under high-temperature conditions, meeting the precise monitoring and control needs of industrial automation.

✅ Durable materials suitable for demanding media

The pressure interface and diaphragm are made of 316L stainless steel, corrosion-resistant, wear-resistant, and impact-resistant. They are suitable for various measurement scenarios such as steam, heat transfer oil, high-temperature hot water, and mildly corrosive high-temperature media, making them resistant to harsh working conditions. The equipment's service life far exceeds that of ordinary pressure transmitters.

✅ Standard signal output with strong installation adaptability

Standard 4-20mA analog output, optional HART protocol and digital output, compatible with various PLCs, industrial control systems, and display instruments. Wiring is simple and installation convenient, supporting multiple installation methods such as threaded and flange, requiring no additional modifications. The original pressure transmitter can be directly replaced, offering strong versatility.

✅ High protection level, worry-free in outdoor conditions

The entire machine has reached IP65 or above protection rating, with excellent waterproofing, dustproofing, and anti-interference capabilities. It can be used in various installation environments such as indoor industrial control cabinets, outdoor pipelines, and boiler equipment, resistant to humidity, dust, and electromagnetic interference, ensuring stable all-weather operation.

3. Applicable Scenarios: Covers high-temperature working conditions across the entire industry

• Thermal and HVAC industry: boiler steam pressure monitoring, high-temperature hot water pipeline pressure measurement, heat exchange station pressure control

• Petrochemical industry: pressure detection of heat transfer oil systems, high-temperature chemical medium pipelines, and high-temperature pressure monitoring of reactors

• Power metallurgy industry: steam pipelines for thermal power plants, high-temperature circulating water systems, and high-temperature pressure measurement for metallurgical equipment

• Industrial boilers / heating: industrial steam boilers, waste heat recovery systems, high-temperature fluid delivery pipelines

• Other high-temperature operating conditions: high-temperature equipment for food processing, high-temperature pipelines for printing and dyeing textiles, and high-temperature pressure monitoring for new energy

4. Core differences between cooler models vs. regular models

Many customers struggle between the regular model and the cooling version, with the core differences clear:

• Conventional pressure transmitter: medium temperature resistant ≤ 80°C, prone to drift and damage at high temperatures, only suitable for ambient temperature media

• Pressure transmitter with radiator: medium temperature resistance up to 200°C, dedicated heat dissipation structure protecting the core, zero faults in high-temperature conditions, service life extended by 3-5 times

As long as the medium temperature exceeds 80°C, prioritize models with radiators, solving the high-temperature measurement problem in one go and avoiding repeated equipment changes and production delays.
